Corrosion du berceau arrière : enquête sur 340 voitures
Où ça commence, jusqu’où ça va d’ordinaire, et où le contrôleur met d’abord la lampe.
The rear subframe on the X400 rusts at the front mount towers and along the forward crossmember. In a 340-car owner survey the first perforation is almost always the driver’s-side front mount, then the passenger side, then the trailing-arm pickups.
A tester’s torch goes to those mounts first. Surface scale is treatable. A hole you can put a screwdriver through is a weld or a second-hand subframe, not a can of cavity wax. UK and TR winter cars fail earlier than dry-state cars; the pattern is the same.
Jacking points are on the subframe. A jack pad on a thin tower will fold it. Use a beam.
